Application fiiea June 19, 1925.1 Serial No. 38,202.

This invention relates to a device for covering round or irregularsections of wire or other articles, With parti eularreference to shapinga flipper strip about a'bead core or wire, either in one continuous ringor in f long lengths.

It is an object of this invention to provide,

an improved machine for covering bead'cores or the. like wherein theedges of the Wrapping strip lap to form an outstanding ridge with theedges offset or evenas desired.

It is also an objectof this invention to provide a segmentvvheel orformer adapted tobe Collapsed over the core or article'to be wrapped topress the fabric tightly therearound either in a circuinterentialwvrapor with a projectingedge as in bead flipping strips. A pressure plateactuated by afcam serves to sequentially operatethe segments of thewheel as they revolve into pos tron.

' It is another objectjof'this-inventlonto provide an idler wheelparallel with the the bead.

Other and further important objects of this invention will beapparentfrom the disclosures in the specification and the accompanyingdrawings. H

This invention (in. a preferred form) is illustrated in the drawings'and' hereinafter more fully described,

ASSl'lOWD on the drawingsz I The specific embodiment chosenforillust-ration shows a continuous cable bead lh for pneumatic tires,about which is" to be Wrappedafiipper strip l6 withthe edges 17 tackedtogether in substantially theplane of thecable bead. More generally thisappara tus is ntended to wrap a coveringmateri'al over a coreo'l more orless irregular outline,

with the core either forming an endless loopor as long continuouslengths. The'covering a material" may be applied as'a complete cir.

, 'cumfe'rential wrap or with projectingedgesf as for-the bead fillerschosenfor illustrative purposes. An adjustable teed table isproF; videdfor the diii'erentwidths of -m'aterial used with. circumferential wr sas pared. with projecting l'appededges, and; also to regulate theoverlap or stagger of the edges, in the 'latte'rgcase. This feedtabl'eQlfS is best shown in F gure IQ h'er-e onejgnide 19 for thejwrapperfabri cis' adjustable'as shown the slots 20. The table a wholeis also a djus'tahleonits supporting armFEZI.

The fabric; is guidedto the table by a bent arm 22 which serves totwilstthe ialoric int position as shown in Figure 2".

The machine proper comprises support- I ing'bracket 23 of a formsuitable for mounting the various elements to be described here inafter.The bracket may be conveniently mounted on a pedestal Qthaving a broadfoot 25 'c'arryingthe operating levers it the" machine is to becontrolledflby the operators foot. The pedestal also carriesa bracket tsupporting the driving motor2T which is.

connected to the operaiting parts of the machine by a frifctionclutch 28operated by the bell crank 29, rod 30 and foot lever 31.

A shaft 32 is fixed at 33' in the bracket 23-;and; carries a pressureplate 34 slidable lengthwise, thereof, I but restrained by the key 35from rotary motion. The pressure plate;

carries a series of free rollers 36 formingan arc of a circle. Betweenthe roller plateand the bracket 23 is a rotating disc; 37 having outlineof the inner or lower part of the object to be wrapped. Secured to thedisc is a segmental wheel 39 of resilient material, each segment ofwhich carries an outstanding block or shoe 40 adapted to be forced overthe peripheral groove 38 when contacted by the rollers 36 to press thewrapping material over the upper or outer surface of the object to bewrapped. The pressure plate is brought into position to act on thesegment wheel by a lever cam 41 acting against the spring pressedplunger 42 in theroller plate. Each shoe 40 of the .segment wheel isbeveled at, its leading edge as indicated at 43 to permit the leadingroller to depress the segment without shock. V Succeeding rollers are sospaced as to prevent release of a segment by one roller before the nextone engages the segment.

An internal gear 44 is secured in the back of the disc 37 and driven bya pinion 45 on I a shaft 46 which in turn is drivenby reduction.

tion gearing 47and worm gearing 48 connected to the friction clutch 28.ticular form of gearing shown is not essen tial, all that is required isto secure a desired peripheral speed of the disc 37 with a con- .venientcontrol by the operator.

WVh-enusing endless bead cores or loops is provided to tension the sameand also to give the disc 87 sufficient driving power on the material.This idler wheel is adjustably mounted in an arm '50 on the shaft 51,which carries a balance weight 52 on another arm 53. This counterbalanceis preferably adjusted to overbalance the idler wheel in orderth'at thewheel may normally return to short position to permit change ofbeadcores after completing the covering. opera- The idler wheel is broughtinto operating or tensioning position by the fluid cylinder 54 andpiston 55 acting on the arm 56. A suitable fluid control valve 57 isshown mounted on the pedestal foot to enable the operator toconveniently control the fluid c linder.

An idler roll 58, having a groove 59 conforming to the shape of'thearticle to be wrapped, is mounted between theffeed table and the disc 37in a position to bring the v wrapping material or flipper strip up be- Iwhether a lap or a circumferential wrap is formed and the feed tablewill also deter mine the stagger of the ends of the strip.

The par The operation is as follows: When wrap ping tire beads, aflipper strip 16 is placed on the feed table with its leading edge overthe idler roll 58, and the bead core 15 placed around the disc 37 andidler wheel 49. Stepping on the control valve 5'7 operates the cylinder54 to tensionthe bead core and forces it into the grooves in the. roll58,

wheel 49 and disc 37. The disc 87 carrying the segment wheel (89) isthen caused to rotate by depressing the foot lever 31 controlling theclutch 28. At the same time, the

lever cam 41 is operated to bringthe presedges of the flipper strip willbe vertical and tangent to the side of the core if a vertical wall isused on the disc 37 as shown. .To get other angles of projection, theprofile of the disc wall and segment shoes are correspondingly inclined.If the flipper strip is to be radial with respect to the bead core aslight change in'th-e profile of the disc groove or a duplication of thesegment whee l acting on the other side'of the bead will accomplish thisresult.

I am aware that many changes may be made, and numerous details ofconstruction may be varied through a wide range with out departing fromthe principles of this in- The ten flipper strip together inpredetermined rela tionship, a peripherally grooved disc adapt ed toadvance said bead core and strip, drivmg means for said disc, a segmentwheel secured to the disc, each segment of which carries a block adaptedwhen forced toward the disc to press one edge of the flipper strip overthe bead core, and means adapted to sequentially depress the wheelsegments to force the blocks into operating position.

2. A machine of the class described comprising means for bringing a beadcore and flipper strip together in predetermined relationship, aperipherally rooved-disc adapted to advance said head core and strip,driving means for said disc, a segment wheel secured to the disc, eachsegment of which carries a block adapted when formed toward the disc topress one edge of the flipper strip over the bead core, a former adaptedto sequentially actuate said block carrying segments and means foradvancing saidformer into operative contact with the segment wheel.

A machine ofthe class described comprising means for bringing a beadcore and flipper strip together in predetermined relationship, aperipherally grooved disc adapted to advance said bead core and strip,driving means for said disc, a segment wheel secured to the disc, eachsegment of which carries a block adapted when forced toward the disc topress one'edge of the flipper strip over the bead core, means adapted tosequentially depress the wheel segments to force the blocks intooperating position, and means adapted to tension the bead core duringthe covering operation.

at. In a machine of the class described, a rotating grooved disc adaptedto receive a portion of an article to be wrapped, a segment wheelsecured to the side thereof, blocks on the ends of each segment adaptedto be passed over the article within the disc groove, and means adaptedto bear against said segments to force the blocksover the article to bewrapped.
